Specification of Letters Patent.

Patented Feb. 1, 1916.

. Application filed August 2;,1915. Serial No. 46,796..

To all whom it may concern:

Be it known that I, HENRY J. Hnwn'r, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain Rubbing-Blocks, of which the following is a specification.

This invention relates to a fountain rubbing block for use in cleaning the fronts or faces of brick buildings and .the like. And the present improvement has for its object to provide a simple and eflicient structural formation and combination of parts, adapting the rubbing block for ready and substantial attachment to its holding head, and in which a flow of fluid through said holding head and rubbing block is attained to aid in the cleaning operation of the appliance, all as will hereinafter more fully appear.

In the accompanying drawings: Figure 1, is a longitudinal sectional elevation, illustrating the preferred arrangement of parts in the present invention. Fig. 2, is a transverse section on line 02-02, Fig. 1.

Similar reference numerals indicate like parts in both views.

Referrin to the drawing, 1 designates the hollow hol ing head of the appliance, preferably of the rectangular form shown, with its interior comprising an upper fluid containing chamber 2, open at bottom, and having an annular or marginal depending skirt 3, forming a lower receiving chamber for the attaching shank of the hereinafter described rubbing block of the appliance.

4 designates an annular shoulder formed at the meeting point of the sub-chambers above described and adapted to form a holding abutment for a gasket or packing 5, as shown.

6 designates a plurality of set-screws, or like holding means, associated with the aforesaid skirt 3 and adapted to fasten the rubbing block above referred to, in place.

7 designates the rubbing block, above referred to, and which is made of any usual and suitable material adapted to have an abradin effect upon the surface of a brick wall. n the present improvement, said block 7 will be preferably formed with an attaching shank 8 adapted to fit within the chamber formed by the above described skirt 3, and held therein by the set-screws 6, aforesaid.

l I Si designates a plurality of orifices passing through the rubbing block 7, for conducting fluid to the rubbing surface thereof.

10 designates a tubular handle of an approximately U-shape, with one end passing through the top wall of the chamber 2 aforesaid, and communicating therewith as shown.

11 designates a holding nut by which said end of the handle 10 is secured in place.

12 designates a controlling valve connected to the other end of the handle 10 aforesaid, and provided with attaching ears 23 for attachment to a side of the holding head 1, as illustrated in Fig. 1.

14 designates a flexible hose attached to the valve 12, and having connection with a suitable source of fluid supply. Said hose 14 in connection with the tubular handle 10, is adapted to conduct to the chamber 2 of the ho ding head 1, a supply of fluid under the required pressure, for use in the rubbing process in which the present appliance is employed.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is

1. In a fountain rubbing block, the combination of a holding head formed with a fluid containing chamber, a depending annular skirt, a tubular handle for said holding head havin communication at one end with the cham er aforesaid, a valve connected to the other end of said handle and adapted for connection with a flexible supply hose, a rubbing block fitting within the aforesaid depending skirt, and means associated with said skirt for fastening the rubbing block in place, substantially as set forth.

2. In a. fountain rubbing block, the combination of a holding head formed with a fluid containing chamber, a dependin annular skirt, a tubular handle for said iolding head havin communication at one end with the chamber aforesaid, a valve connected to the other end of said handle and adapted for connection with a flexible supply hose, a rubbing block fitting within the aforesaid depending skirt, and a plurality of set screws passing through said skirt to engage said rubbing block, substantially as set forth.

3. In a fountain rubbing block, the combination of a holding head formed with a fluid containing chamber, 21' depending annular skirt, a tubular handle for said holding head havin communication at one end with the chamber aforesaid, a valve connected to the other end of said handle and adapted for connection with a flexible supply hose, 0. rubbing block having a shank portion fitting within the aforesaid depend- 1n sklrt, and means associated with said sklrt for fastening the rubbing block in place, substantially as set forth.

Signed at Chicago, Illinois, this 21st day of August, 1915.

HENRY JAMES HEWITT.
